Definitions

  • Concrete is a composite material, comprising a matrix of aggregate (typically a rocky material) and a binder (typically Portland cement or asphalt), which holds the matrix together. Concrete is one of the most frequently used building materials and is said to be the second most widely used material on earth, after water.
  • a matrix of aggregate typically a rocky material
  • a binder typically Portland cement or asphalt
  • the invention provides a method for producing a mechanochemically carbonated clay, said method comprising the steps of:
  • This method can be applied to various types of clay precursors, advantageously resulting in unique mechanochemically carbonated clay.
  • the invention provides a mechanochemically carbonated clay obtainable by certain embodiments of the method for producing the mechanochemically carbonated clay, as set out in the appended set of claims.
  • the water demand is decreased compared to pure cement, as well as compared to cement filled with non-carbonated clay.
  • This is particularly surprising in view of the reduced particle size of the mechanochemically carbonated clay compared to the non-carbonated clay.
  • a reduced particle size is generally associated with an increased water demand.
  • the reduced water demand as compared to untreated feedstocks or pure cement may contribute to improved properties such as workability, compressive strength, permeability, watertightness, durability, weathering resistance, drying shrinkage and potential for cracking.
  • limiting and controlling the amount of water in concrete is important for both constructability and service life.
  • the present invention allows to have better control over the water demand.
  • the mechanochemical process of the invention may result in an increase in amorphous content when analyzed by XRD wherein at least some crystalline domains which may be present in a feedstock are maintained via an internal architecture in the form of microcrystallinity, which persists in a more generalized disordered structure.
  • This disordered macro structure thus, promotes higher reactivity and improves cement hydration.
  • the production of the mechanochemically carbonated clay relies on a cheap CO 2 capture technology platform capable of operating on dilute CO 2 streams, such as directly on a point source emissions of a combustion plant, such that a filler is provided which can be produced in an economically viable manner and which combines both the CO 2 emission reduction achieved by reduced cement production and the CO 2 emission reduction achieved by CO 2 sequestration.
  • the mechanochemically carbonated clay of the present invention in particular the mechanochemically carbonated clay of the invention, constitutes an excellent filler for many applications, combining distinct mechanical properties with a cost-efficient CO 2 capture technology.
  • the invention provides a composition comprising a mechanochemically carbonated clay as described herein and a further material selected from the group consisting of asphalt, geopolymers, cement, polymers and combinations thereof.

  • the hydrous aluminium phyllosilicates are preferably selected from the kaolin group, the smectite group, the vermiculite group, or mixtures thereof.
  • the clay may be calcined or non-calcined.
  • mechanochemically carbonated clay is used herein to refer to a clay obtainable by the mechanochemical carbonation method of the present invention.
  • the BET surface area as referred to herein is determined at a temperature of 77K using a sample mass of 0.1-0.5g.
  • the BET surface area as referred to herein is determined using nitrogen.
  • a preferred analysis method to determine the BET surface area comprises heating samples to 400 °C for a desorption cycle prior to surface area analysis.
  • a suitable and thus preferred analysis apparatus for determining the BET surface area is a Micromeritics Gemini VII 2390 Surface Analyzer preferably equipped with a Micromeritics FlowPrep 060 flowing-gas degassing unit.
  • the Total Carbon (TC) content referred to herein is preferably determined in accordance with the method described on Soil Sampling and Methods of Analysis, 2nd Ed., CRC Press (2008), p. 244 and further, incorporated herein by reference.
  • the Total Carbon (TC) content is always expressed herein as wt.% based on the total weight of the composition being measured, i.e. based on the total weight of the clay precursor, or based on the total weight of the carbonated clay.
  • the compressive strength, strength-activity index and water demand as referred to herein is determined in accordance with ASTM C311/C311M-22.
